Color Rendering Index (CRI) Versus Color Temperature-What ar

2018-12-04 17:43 Admin

Over the past few years, there has been a complete confusion over the difference between color rendering index and color temperature.
But here in this article, we will clarify your doubts between the two and simplify your understanding of the same.

What is Color In General?

Color is nothing but a property of light that can be seen by the naked eye.
It is of great importance to notice that even the most brightly colored object when placed in a dark room displays no color at all.
Therefore, light is the most important aspect that decides if a color can be seen or not.

How Many Types of Colors Do Exist?

We have primary colors and secondary colors. Primary colors are mixed in order to form secondary colors. Some of the most
important colors known to mankind are the following: Red, Orange, Yellow, Green, Blue, Purple, Brown, Black, White, and Grey.
There are many instances wherein people tend to believe that a specific room should have a certain color and so on.
The different reasons could be either due to religion or just the fact that some people are really in love with a certain color.
We will discuss that a little later in this article but for now, let’s get started about the difference between color rendering index and color temperature.

What is the Color Rendering Index (CRI)?
The simple definition would be the ability of a light source to precisely display all the possible frequencies of a certain spectrum as compared to the color temperature. 
It is ideally rated on a scale ranging from 1-100. Natural sunlight has the highest CRI of 100, while LED lights nowadays have the range from 75 to 90.
Higher CRI is more expensive in general.
The lower the CRI the less accurately will the colors be reproduced. The light sources that have blazing radiators tend to have
a CRI of about 100 since all the colors in the CRI spectrum are shown equally in its form. For example, you can see an apple has “wine red” color under sunlight,
they will have “dark pink” color under the low CRI lights. What is the importance? For some special occasions such as art gallery and museum, the lighting requires
up to 95+ CRI to allow the visitors to see the “real” colors.

What is the Color Temperature?

It is defined to be the simplest method of describing different color characteristics of light; that includes Warm (yellow toned) and Cool (blue toned) colors measured in degrees of Kelvin.
The higher the degree Kelvin, the whiter the color temperature. However, the white lights will appear brighter than those of a lower Kelvin degree.And thus, CRI affects the color of the
object we perceive while color temperature is the color of the lights emitted.
They are completely different parameters describing the nature of a light source.

The Types of Lights and When to Apply Them?

a. Soft and Warm White

These are best suited for the bedroom and living room in particular.
 It gives a sense of warmth and a cozy feeling to the room.

b. Bright and Cool White

These generally work very well in kitchens, bathrooms, and backyards.
They definitely make the room look brighter, whiter and give a sense of positive energy feels.

c. Daylight

They are also used in the bathroom, kitchen, and garages. They can be used as reading lights or even
when you want to sit down and do a project. If you’re a lady and you love applying to make up,
then this one is meant for you. It’s my personal favorite.

2. Interior Designers Have a Way of Getting it Done

Interior designers have a huge role to play when it comes to deciding the color and texture of the rooms and their lighting.
Lighting in a room changes two things; one is the ambiance of the room and second is the sizing of the room.
Great lighting can make your room look bigger while a certain type of lighting can actually make your room look smaller. So choose well.
The placement of furniture and color of the same walk hand-in-hand for an interior designer. The room size, the type of furniture and the natural lighting;
all play an equal and important part in making a room look the way it should.
